Hi,
The following patchset contains Netfilter/IPVS updates for net-next:
Patch #1 to #11 to shrink memory consumption for transaction objects:
struct nft_trans_chain { /* size: 120 (-32), cachelines: 2, members: 10 */
struct nft_trans_elem { /* size: 72 (-40), cachelines: 2, members: 4 */
struct nft_trans_flowtable { /* size: 80 (-48), cachelines: 2, members: 5 */
struct nft_trans_obj { /* size: 72 (-40), cachelines: 2, members: 4 */
struct nft_trans_rule { /* size: 80 (-32), cachelines: 2, members: 6 */
struct nft_trans_set { /* size: 96 (-24), cachelines: 2, members: 8 */
struct nft_trans_table { /* size: 56 (-40), cachelines: 1, members: 2 */
struct nft_trans_elem can now be allocated from kmalloc-96 instead of
kmalloc-128 slab.
Series from Florian Westphal. For the record, I have mangled patch #1
to add nft_trans_container_*() and use if for every transaction object.
I have also added BUILD_BUG_ON to ensure struct nft_trans always comes
at the beginning of the container transaction object. And few minor
cleanups, any new bugs are of my own.
Patch #12 simplify check for SCTP GSO in IPVS, from Ismael Luceno.
Patch #13 nf_conncount key length remains in the u32 bound, from Yunjian Wang.
Patch #14 removes unnecessary check for CTA_TIMEOUT_L3PROTO when setting
default conntrack timeouts via nfnetlink_cttimeout API, from
Lin Ma.
Patch #15 updates NFT_SECMARK_CTX_MAXLEN to 4096, SELinux could use
larger secctx names than the existing 256 bytes length.
Patch #16 fixes nfnetlink_queue with SCTP traffic, from Antonio Ojea.
Patch #17 adds a selftest for SCTP traffic under nfnetlink_queue,
also from Antonio.
Patch #18 adds a selftest to exercise nfnetlink_queue listeners leaving
nfnetlink_queue, from Florian Westphal.
Patch #19 increases hitcount from 255 to 65535 in xt_recent, from Phil Sutter.
